In British military forces, a unit consisting of marines and soldiers organized for rapid deployment and trained to conduct special operations.
The commando originated with the Boers in South Africa, where it was the administrative and tactical unit "commandeered" by law. In World War II the British adopted the term for a new specially trained amphibious raiding force. Modern commandos are units of the Royal Marines with support troops from the British Army; by extension a member of such a unit is also called a commando and is entitled to wear a green beret.
